lgure 2 shows an inverted plan und Un applying our invention to the removal 105 Figure 3 shows an end elevation respectively, of Wallpaper :tor exemple, the steein supplT on un enlarged soule oi the device shown. in is turned on und the device 3 applied to the Figure l, While surface to be operated uponm The steein issues from the nozzles 11, in fine jets, pierces the paper and raises it trom the wall. The rubber strips 13 ret-ain the water ot condensation which assists in softening the paper. By traversing the device 3, over the wall by means of the handle 7, the paperI is divided by the steam jets issuing from the nozzles 11 into a number or narrow strips, which may then be removed troni the wall by any suitable means.

In further explanation ot the application of the invention as above described, attention is directed to Figs. 1 and e, from which it will be noted that the ducts 8 are in direct communication with the boiler 1 by the pipe 2 when valve 4L is open, and that the outlets for steam from the ducts 8 are only through the nozzles 11, which are very small. A substantially high pressure et steam may be maintained in the ducts 8 by this construction, and iinejets or' substantially cylindrical form having a high velocity will issue from the nozzles and pierce the wall covering. After piercing the wall covering, the jets will impinge against the wall surface and subsequently between the wall and Ythe back ofthe wall paper between the jets, so that the paper willbe separated from the wall. As the device isimoved along the wall, these line jets cut the paper into strips and separate these strips from the wall as above described by the steam passing` through the cut portion and entering between the wall and the back of the paper in between the j ets vfor forcing the strips away from the wall.

In some cases, instead et the iorm et device above described, we may construct it as shown in Figures 7 to 9. In these Figures, the device 3 is provided with a single duct 17, for the steam, the inlet ends being threaded at 18, for connecting up to the pipe 2, while the outlet end of the duct is partially closed by the plate 19.

The plate 1,9 has three slotted holes 2O formed therein, through which the screws 21 pass, tor securing the plate to the device, the width of the orifice 22 through which the steam issues, being determined by the thickness of the lead toil 2-l, or other material used in jointing the plate 19 to the cast-ing 8.

The orifice is formed by omitting` the jointing material along the itront edge of the outlet of *he duct 17.

The front edge ot the plate 19, is bevelled as shown, so that the edge 23 may be used as a. scraper for the removal of the paper.

The sectional dimensions of the oritice for the steam may, for example, be about three inches long by one sixty fourth ot' an inch wide.

On applying this modification of our invention to the removal oi-x wall-paper, the device after the steam has been turned on. is applied to the surface to be operated upon.

As the steam issuing Afrom the device cuts or pierces the wall-paper, the device is manipulated so that the edge 23, acts as a scraper to remove the paper.

The steam used in conjunction with the devices as above described, may be either saturated or superheated. ln the latter case, the boiler is pro vided with means 'for imparting to the steam the desired degree oi superheat. Vilhcn supcrheated steam is used in addition to increasing` the elliciency of the device, it also acts as an elicient germicide and insecticide.

ln some cases we may attach a removable container 25 Figure l, lor a disinfectant under pressure, to the devices as above dcscribed, se that the steam will interminglc with disinfectant from the coiltainer and spray it on to the walls during the process.

By means ot our invention, wall-j mper. white-wash, and distemper may be removed 'from the walls ot' buildings, in an easy und expeditious manner, while the jets at the same time el'liciently disinfect the surfaces.

ln the foregoing specification and the claims appended hereto, we have used the term buildings in its generic sense, and intend it to include stiuctures both of a permanent and temporary character.

le wish it to be understood that the above examples of our invention, are simply to be regarded as typical only, and not as in any way limiting our invention theretoas modifications may be made in the dimensions of the orifices and other details without departing beyond the scope ol' our invention.

le claim:

1. A method of removing wall coverings consisting in leading a supply ot elastic iiuid under pressure to the operating position and projecting said elastic Huid in one or more jets against the covering being treated so as vto pierce the covering, impinge on the wall and subsequently flow between the covering and wall and raise .said covering from the walls.

2. A method ot removing wall coverings consistingin leading a supply of steam under pressure to the operating position and projecting' said steam in one or more jets` against the covering being treated so as to pierce the covering, iinpinnje on the wall beneath said covering and 'liow laterally to the jets along the wall beneath the covering and raise said covering 'from the walls, as set forth.

3. A method ol removingwall coverings consisting in leading a supply of superheated steam to the operating position and projecting said steam in one or more jets against the covering being;` treated. so as to pierce the covering, impinge ou the wall beneath said covering and iiow laterally to the jets along the wall beneath the covering .'f

llO

i cn

Laaneea andraisesaid covering from said Walls, as set forth.

4l. l inethod ot removing' Wall coverings, consisting in directing a heated moist fluid against the cover-nig along` a series of spaced lines, whereby to penetrate such covering along such lines and directing suc-h :Huid between said covering` and Wall surface throughout the area of covering between the lines of penetration.

5. l method ofseparating Wall coverings iiroin the Wall surface7 consisting in directing a fluid under pressure to pierce such covering,l to permit such Huid toimpinge on the wall surface and be thereafter directed between said covering and Wall surface beyond the jet for raising the paper from the Wall.

G. fr device for removing Wall coverings having in combination a source of heated fluid under pressure,`a plate having ducts p therein, nozzles mounted in the ducts, and

a hose for conve ino' the tluid under ressure to said ducts7 `whereby the nozzles Will confine the fluid directed therethrough `in separated jets tor piercingthe Wall covering.

7. A device for retrieving- Wall coverings having in combination. a source olf fluid under pressure, a plate formed with a plurality of ducts7 a connection for conveying` said tluid to said ducts under pressure, and a `phirality of jet nozzles mounted in the plate and communieating` with said duets9 whereby `when the plate is inoved over the Wall covering in operation, the jet nozzles will contine` the fluid issuingtherel'lroln in tine spaced streams for piercing and removing the covering,` from the Wall.

ln testimony whereof We have signed our naines to this specicatlon.
